Tohoku Rakuten Golden Eagles right-hander Masahiro Tanaka received a certificate of recognition Saturday by Guinness World Records for his record-breaking season.

The 25-year-old Tanaka went 24-0 this season and, coupled with his 28-game winning streak that began on Aug. 26, 2012, plus two wins in the postseason, had a 30-game winning streak.

"I've never thought about a Guinness record. I've watched on TV and thought, 'So this is what a Guinness record is.' It is a great honor to be recognized and have my name recorded in history," said Tanaka, who received the certificate at a fan appreciation event the same day at Kleenex Stadium in Sendai.
